The Chamois is there because the shorts can't breathe .....LOL Hahaha (buy some creme to absorb all that sweat they are causing)

They are aerodynamic though.

Nice side benefit of cycling shorts is the option of extra padding to counteract the hardness of a bling race saddle.

P.S. This reminds me of that "proportional Crank length BS" because people can never figure that out either. (not directed at you-statement in general)
